Description
Die Erfindung betrifft einen Adsorptionstrockner für gasförmige Medien, mit zwei Adsorberkammern, die jeweils einen Adsorber mit einer Feuchtigkeit adsorbierenden Oberfläche enthalten, und mit einem Ventilsystem, das dazu eingerichtet ist, zu trocknende, unter erhöhtem Druck stehende Luft abwechselnd durch eine der Adsorberkammern zu leiten und einen Teil der getrockneten Luft nach Entspannung durch die jeweilige andere Adsorberkammer zu leiten, um den darin enthaltenen Adsorber zu regenerieren. The invention relates to a adsorption dryer for gaseous media, with two adsorber chambers, each containing an adsorber with a moisture adsorbing surface, and with a valve system, which is adapted to be passed to be dried, under elevated pressure air alternately through one of the adsorber and to pass a portion of the dried air after relaxation through the respective other adsorber to regenerate the adsorber contained therein.
Insbesondere befasst sich die Erfindung mit einem Adsorptions-Drucklufttrockner für die Erzeugung von trockener Luft zum Trocknen von Kunststoffgranulat. In particular, the invention is concerned with an adsorption compressed air dryer for the production of dry air for drying plastic granules.
Ein Beispiel eines herkömmlichen Adsorptionstrockners dieser Art wird in
In
Der Zylinder ist in einer Trommel angeordnet, deren Querschnitt einlass- und auslassseitig in mehrere Sektoren unterteilt ist. In einem Sektor wird die zu trocknende Luft axial durch die Trommel und durch die Wabenstruktur des Adsorbers geleitet, während in einem anderen Sektor die zu regenerierende Luft durch den Adsorber geleitet wird. Aufgrund der Drehung des Zylinders kommt es so in jedem Teil des Adsorbers zu einem periodischen Wechsel zwischen Adsorptions- und Regenerationsphasen. The cylinder is arranged in a drum whose cross-section is divided into several sectors on the inlet and outlet side. In one sector, the air to be dried is passed axially through the drum and through the honeycomb structure of the adsorber, while in another sector the air to be regenerated is passed through the adsorber. Due to the rotation of the cylinder, there is a periodic change between adsorption and regeneration phases in each part of the adsorber.
Aufgabe der Erfindung ist es, einen Adsorptionstrockner zu schaffen, der einfach aufgebaut ist, nur einen geringen Wartungsaufwand erfordert und es erlaubt, getrocknete Medien mit verbesserter Qualität zu liefern. The object of the invention is to provide an adsorption dryer, which is simple in construction, requires only a low maintenance and allows to deliver dried media with improved quality.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jeder der Adsorber ein starrer Körper mit wabenförmig angeordneten Kanälen ist, deren Oberfläche aus einem Feuchtigkeit adsorbierenden Material besteht. This object is achieved in that each of the adsorber is a rigid body with honeycombed channels whose surface consists of a moisture adsorbing material.
Aufgrund der Wabenstruktur des Adsorbers kommt die Luft auf einer sehr großen Oberfläche mit dem Feuchtigkeit adsorbierenden Material in Kontakt, so dass eine ähnlich hohe Trocknungsleistung erreicht wird wie bei herkömmlichen Adsorbern, bei denen das adsorbierende Material durch eine Schüttung aus Kugeln gebildet wird. Da die Adsorber keine mechanisch beweglichen Teile aufweisen, wird ein einfacher Aufbau und eine geringe Störanfälligkeit erreicht und der erforderliche Wartungsaufwand reduziert. Ein wesentlicher Vorteil besteht darin, dass die getrocknete Luft weniger stark mit Staubpartikeln belastet ist, die bei herkömmlichen Drucklufttrocknern mit Partikelschüttungen dadurch entstehen, dass die lose geschütteten Partikel durch die durchströmende Luft in Vibration versetzt werden und aneinander reiben, so dass staubförmiger Abrieb entsteht. Due to the honeycomb structure of the adsorber, the air on a very large surface comes into contact with the moisture adsorbing material, so that a similar high drying performance is achieved as in conventional adsorbers, in which the adsorbent material is formed by a bed of balls. Since the adsorber has no mechanical moving parts, a simple structure and low susceptibility is achieved and reduces the required maintenance. A significant advantage is that the dried air is less heavily contaminated with dust particles, which arise in conventional compressed air dryers with particle beds in that the loose particles are caused by the air flowing through vibration and rub against each other, so that dusty abrasion occurs.
